Application August 26, 1946, Serial No. !i93;.05 1 'solaims. (c1; 1:92-47) This invention relates to -clutches and more particularly to positively acting clutches of the itype especially adapted for transmitting driving dorce from a rotatable axle tor shaft to a drum or reel carried thereby.

"The :g'eneral object of the invention is the pro-- ivision of a novel and improved clutch of this type-which is of rugged and simple construction, economical to manufacture and :maintain, capable of positive :actionwithmo danger of slippage and :not subject to injury or obstruction by oil, dirt, grease, or water. i

In preferred embodiment the invention contemplates the provision of a disc rotatable ion a drive "shaft, the disc leeing the 'driven element of the clutch :antd comprising a rigid {portion or n tgear,j1pulley,-drum or reel or any other member --to which :power is to be :applied from the shaft. line driving {portion of the clutchiassembly oom- "prises :a-drive member :fixed to the shaft, extendlin-g a plane transverse ithereto, and ,provlde'd with guide openings ifor the projectible :pln -or bolt elements \of the clutch. -A pin-carrier is slidably mounted on the shaft and the =clutc'h "pins are pivotally :mounted =upon radially ex- .tended portions thereof. The engagement of the pins within the openings in the drive :member inned tothefshaft causes thepin-Ycarrier'to rotate with :the shaft although itis :also slidable relative thereto. fl he pin-carrier is adapted to be enigaged'by ashifting yoke'swhereby the carrieria-nd, therefore, the ,pin elements, may be :projec'ted through the drive member :and into engagement with the driven element of the clutch assembly.

.The driven disc is provided with fnovel socket .portions within which ltheepins are adapted ifiO -be :projected, and means are also provided :for :strengthening-and reinforcing therdisc and'socket :struoture and for sdisengagingthe .pins -from the disc 'upon reverse-movement oi the (latter.

-Qther objects and features iof :novelty :will :be apparent from -the following specification when read 'in connectionwith the :accompanving idraw- :;-ings in which one embodiment of the SiIlVGIltiOll FiS illustrated by -way of example.

'I-ntthe drawings:

Figure 1 is a view inielevation 'OfEa dIiVB'TfOT a winding drum which embodies a clutch constructed and \operated in accordance with the principles of the invention, a portion of the winding drum being "shown lin section;

Figure .2 is atransverse vertlcalsectional view taken on line 2-2 ofFigure hand Figure 3 is a similar view taken on line 3--3 of Figure 1.

In the embodiment illustrated in the drawings, theinvention is applied "to .a winding-drum or .fre'el, "but it'is understood that such illustration ;:is"'for example only and the novel clutch may the I applied to any type of {driven element which its adapted to "be operatively linked to :a drive shaft. The lclr-um ortreel indicated generally "by the reference numeral d0 comprises a .cy1in drical drum core LI to the ends of which are -:connected, .as bvmeans of welding, :the end plates A2 and 43. Centrally of the end plates -.thei:e are provided cylindrical drum bushing carriers 44 which may be Welded -or otherwise secured within central openings :in the end plates '42 and t3. Within the bushing carriers 14 there are disposed the bearing bushings 1.5 by means of which the drum or reel 40 is rotatably :mounted upon the drive shaft 46.

The :drive shaft to .is .mounted the bearin I1 and 18 which are supported by the pedestals l9 and 20. The shaft is adapted to be rotated from any suitable source ref power and for this purpose the shaft is provided with the key .or spline slots .2! adjacent its ends.

The end plate .or disc 42 comprises the driven member of the clutch :assembly, and, of pourse, within the broadest scope of the invention, this disc .or driven member-maybe a :part of any type .of driven device harried by the shaft, whether :a pulley, drum, gear, or the like. Means are provided on the neuter face of the disc 12 for engagementby the movable pin'elements. These means comprise ,the semieeyllndrieal rsocket 2e16- ments 125 which are welded oriotherwise secured at diametrically opposite points -on the enter face of the disc. In order to brace and reinforce these sockets elements, and to \serve a murpose which will be described later, there are provided arcuate wedge or cam-like plates or iflbSsZB welded ,to the faceaof the disc l2 and abutting the-socket elements :25.

At a point adjacent the position .of the end -disc I2 of the drum, upon the drive shaft ii, there is fixed :to the shaft :a transversely nex- -tendingdrive member 30, whichl'inlthe illustrated embodiment, comprises a sturdy :bar :or plate provided with a centralnpening through which :the

shaft extends. A flange [31' surrounds the shaft and is welded' to both the bar and the shaft 16. :In order to .rfurther rigidity the shaftand drive member .30 the .zflange :3! is provided with (a rectangular opening 132 :to :provide additional welding surfaee'betweemthe shaft and the flange.

Adjacent 'th'eaends :of the drive -bar3ll, there are provided openings :around which are 'fixe'd the tubular :or nylindrical sleeves or collars "*3! which :provide additional guiding support "for the .proiectible pin :or 'boltelements '35.

Slidably amounted on the *drive shaft l-B "between the drive ibar 13 0-and theibearing "H is the collar :31 whioh is provided with the oppositely extending rigid arms 38 which "are forked at the onds Fas at :39 ':to embrace the pins 35, tons W0 providing pivots for the locking pins 35. The aeollar 131 Li's 'circuinferentidlly grooved adjacent tits nlefthand iend was viewed in Figure 1 '-'and withtin "this {groove selamped the "split ring M2, *the 48. The shift yoke is provided at its bend with a plate 49 which is secured to the actuating shaft 50 which may be carried in suitable bearings 51.

In actuating the clutch, the rod or shaft 50 'same direction through the guide openings in the drive bar 30 and are retracted from the socket elements on the driven disc 12, whereupon the reel or drum I0 is disconnected from the shaft Hi. When the pin-carrier 31 is moved toward the right in Figure 1 by the appropriate rocking of the shaft 50, the pins 35 are projected from the openings in the drive member so that they will engage in the semi-cylindrical sockets 25 and serve to rotate the driven disc l2, and the reel of which it is a part, in the direction of the arrow A in Figures 2 and 3 of the drawings.

A further function of the inclined bracing elements 26 associated with the sockets 25 will now be described. These elements are in effect cam members which, if the shaft 16 were to rotate in a direction opposite to the arrow A, would cam the ins out of engagement with and reverse the movement of the clutch actuating members. A similar result would occur if the reel in were to overrun the driving member 30 and the shaft 16 in the direction of the arrow A.

Various changes and modifications may be made in the embodiments illustrated and described herein without departing from the scope of the invention as defined by the following claims.

Having thus described the invention, what is -z claimed as new and desired to be secured by Letters Patent is:
